Re: Silver coins
It is a fireproof brick! Looking at a piece of wood ( being polite ) on top of a washing machine in your workshop or work area Screams soo many fire risks. You will have Silver spill. You will have it splutter.
You need to be able to safely protect yourself and your house from this.
Firebricks are CHEAP and are light weight. They are in my opinion a MUST have.
I wouldn't bother with stamps yet. I would get pouring first. And for the love of god only use 999 ... Never use in a furnace... ( Not just crucible ) any other metals!!! or substandard metals! It will contaminate it and cause it to fail a assay or legally need to be classed as a white metal.
Finally get a powder fire extinguisher. They are cheap and will work with electrical fires and help put out molten metal, Ideal if your graphite crucible breaks into your furnace.
Just a heads up... Safety first bud. I can not stress that enough.

Re: Silver coins
You didn't do anything wrong. Remember that when you are melting the grain you need to account for a small loss. For 2oz I suggest putting in 1 or 2 grams extra. Why? Because you will have some loss in the graphite and a tiny loss from evaporation. Yes small amounts! This is why you should only use that furnace for 999 silver or 999 gold each furnace should be assigned for 1 metal and purity. BYB poured 999 gold but because he used his silver furnace it was not 999. He is a good pourer and a perfectionist. It was a mistake but a lesson learnt and a massive wake up call to all other pourers.
If your after a 2oz bar remelt it in the furnace and add 1 or 2 grams. You will need to account for cleaning as well. If you are going to register and get it assayed they might drill it.

Be Extra carefull!!! I have learnt the HARD way with using sandpaper... I failed a assay because I used very fine paper which had traces of Palladium, Rhodium, Aluminium and Iron oxide.
I now only finish my pieces after they are assayed!!!
That was a hard lesson to learn.

Re: Silver coins
The black is Graphite and should come out. But really good work. Don't stamp them unless your just want to practice. Are you using Borax
Anyway well done again ...
